I'll add some criticism to the plaudits above:
Haskil - Not lively. Understated to the point of moribund.
Rudolf Serkin (on DG) - Please. Unattractive pianism mars superb accompaniment by Abbado (an underrated Mozart conductor, IMHO).
Brendel - He's always OK but his early set done in the 1960s with Viennese pick-up orchestras has a brio and sparkle that is missing from the later recordings.
For me, the Perahia and (older sound) Casadesus recordings are always the standard.
